Actually, Bray-2 and Reams extractions are related. Bray -2 extracts most of
the exchangeable pool of nutrients from the soil, while Reams extracts pull
out only the easily exchangeable nutrients.

Neither gets the full set of nutrients that are present in soil.

All these different soil extract methods are trying to assess some aspect of
the nutrients in soil. You have to know exactly what is being extracted in
order to know how to interpret the information.

OK?
